Catalogue against catalogue
An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary
AU Optronics (AUO) is a Taiwanese company headquartered in Hsinchu, founded in 2001 primarily as a flat-panel display manufacturer that expanded into photovoltaics under its AUO BenQ Solar brand. Its solar panels have received certifications including CEC clearance for the US market and recognition from Taiwan's Ministry of Economic Affairs for high-efficiency dual-glass modules developed in collaboration with Sino-American Silicon Products. However, no confirmation of BloombergNEF Tier 1 bankability status was found in available sources, and its solar production footprint appears modest compared to leading Chinese manufacturers. TCL, operating through its subsidiary TCL Zhonghuan and its TCL Solar module brand, is a Chinese manufacturer headquartered in Tianjin with deep vertical integration spanning silicon wafers, cells, and modules. TCL Zhonghuan was confirmed on BloombergNEF's Tier 1 list as of Q3 2025, a significant institutional endorsement. In terms of global footprint and bankability recognition, TCL Zhonghuan holds the stronger position.
AUO BenQ Solar serves residential, commercial, and utility segments, with recent award-winning products focusing on large-format bifacial dual-glass modules designed for weather resistance. Its catalog has historically been positioned toward premium or specialty applications in Taiwan and select export markets, though its consumer-facing presence internationally remains limited. TCL Solar covers a broader product spectrum with considerably more current technology detail publicly confirmed: its TOPCon T5 Pro series offers configurations for utility-scale ground mounts up to 760 W, commercial and industrial rooftops up to 680 W, and residential systems up to 480 W, with efficiency reaching 25.17% in that line. The company also showcases back-contact (BC) modules achieving over 25.2% efficiency at SNEC 2025, backed by a portfolio of more than 1,600 BC-related patents. TCL additionally offers a 25-year product warranty and a 30-year linear performance warranty, which is a competitive warranty stance by current industry standards.
For most buyers in 2025 seeking a well-documented, bankable panel with a broad range of current-generation TOPCon and back-contact options, TCL Solar is the more straightforward default choice, given its confirmed Tier 1 status, verified high-efficiency specifications, and publicly available warranty terms. AUO BenQ Solar may be a reasonable option in markets where Taiwanese supply chains are prioritized or where specific government certification programs favor it, but the lack of published Tier 1 recognition and limited independent reviews make it harder to recommend broadly without additional due diligence.
